Corn sheller

The modern corn sheller is commonly attributed to Lester E. Denison from Middlesex County, Connecticut.

Denison was issued a patent on August 12, 1839, for a freestanding, hand-operated machine that removed individual kernels of corn by pulling the cob through a series of metal-toothed cylinders which stripped the kernels off the cob.

Soon after, other patents were granted for similar machines, sometimes having improvements over Denison's original design.

Corn shellers can be powered by a hand crank, a tractor, a stationary engine, or by an electric motor.

The kernels fall out through a screen into a container (such as a bucket) placed underneath the machine.
